JOSHUA SANDAGE, OF CARPENTERSVILLE, ILLINOIS.

WAGON-AXLE SQKEIN.

SPECIFICATION forming part of Letters Patent No. 256,744, dated April 18,1882.

Application filed September 11, 1880. (No model.)

To all whom it may concern Be it known that I, JOSHUA SANDAGE, of Carpentersville, in the coun ty ofKane and State of Illinois, have invented a new and useful Thimble-Skein for Wagon-Axles, of which the following is a specification.

This invention relates to thimble-skeins (Illployed in the manufacture of wagons; and it consists in a skein produced from plate material, which will be hereinafter more fully descrihed.

In the accompanying drawings, Figure 1 is an isometrical representation of a thimbleskein embodying my invention, of which Figi 2 is a longitudinal central section. Fig. 3 represents the blank from which to form the thimble-skein. Fig. 4 represents a ring employed to form the collar, of which Fig. 5 is a section on dotted line m. Fig. 6 is a transverse section of the thimble on dotted line Fig. 7 is an isometrical representation of the screwthreaded plug employed to close the outer end of the skein. The following figures, from 8 to 11, inclusive, refer to a slight modification of my improved skein, and of these figures, Fig. 8 represents the blank from which to form the modified skein. Fig. 9 represents the same blank having its transverse central portion raised in rib form to produce the collar of this blank. Fig. 10 is'a longitudinal section on dotted line 11 and Fig. 11. is a longitudinal section of the finished skein.

The blank represented at Fig. 3, from which to form the thimble-skein, is cut to proper size and form from suitable plate material, preferably'from plate-steel, and for the purpose of a more clear description I shall divide it into the several sections A, B, O, and D. Of this blank, the section A, bounded by the side lines a and end lines 12, is of proper form and size to produce the skein portion E of the thimbleskein when properly bent in tubular or thimble form. The section B, bounded by the side lines a and end lines cl, is designed to form the enlargement on the upper side of the inner end portion,F, of the thimble-skein. The sections O,bounded by the end lines, band (I, and the side lines 0, are designed to form the enlarging curved portions G immediately under the collar on the upper side of the thimble and connect the skein proper with the inner enlarged end portion of the thimble. The portion D of the blank, bounded by the sidelines fand end line g, forms the portion H of the thimble-skein, which extends inward on the under side of the axle-tree. This blank is bent in cylindrical or thimble form, having its axis lengthwise of the blank, and in such a manner that the side edges of the sections A, B, and (J overlap each other and are welded, producing a lap-weld, as represented by thcdotted line 2 in Fig. 6, through the length of thethimble.

At h is represented a plug of suitable material and of proper size to fill the'tubular outer end of the skein portion, inwhich it is placed,

being put in posit-ion by passing i't through the thimble from its enlarged end. This plug is fixed in position in the tube by welding the parts. The outer portion,i, of this plug is reduced to a proper size, forminga shoulder against the end of the skein, and the reduced portion is screw-threaded to receive a screwnut, (represented at 1a,) which is of the usual form and employed for the purpose of holding the wheel on the skein in the manner common in thimble-skeins. This screw-plug is also proskein-bolt to fix it on the axle-tree in the usual manner.

At I is represented a collar made of suitable material and of proper ring form and size to embrace the thimble-skein at the junction of the enlarged portion of the thimble with the skein portion th ereof. This ring-formed collar may be fixed in position on the thimble by welding it thereto; or, instead of welding, it may be fixed by the usual means of shrinking it on the thimble-skein.

I also produce 1n yimproved skein from plate material without the employment of the separate ring-collar hereinbefore described, and thisIaccomplish by the employmentof a blank, (represented at Fig. 8,) which is substantially the same as the blank represented at Fig. 3, hereinbefore fully described; but in producing the thimble-skein from this blank the portion 0, embraced between the transverse lines m and sidelines n, is raised, as represented in Figs. 9 and 10. This blank, with its raised portion 0, is then bent in tubular or thimble form in the same manner as described in connection with the blank at Fig. 3, having its side edges overvided with an axial hole, as at l, to receive a lapping and welded, and having the raised portion 0 closed and welded, producing a thimble-skein, as represented in Fig. 11, having the thimble and collar 0 produced from the same blank of plate material of a single piece.

From the foregoing it will be seen that my improved thiinb-le-skein, made from plate material, consisting of the skein proper, on which the wheel revolves,'bein g that portion between the collar and the screw-nut, and the enlarged thimble portion from the collar to its extreme open end to receive the enlargement of the axle-tree, form a thimble in every particular substantiallyidentical with the approved form of the cast thimble-skein in general use in the manufacture of wagons; but by the employ meat of malleable plate material I produce a morereliable thimble-skein, and when platesteel or steel-laced iron plates are employed I am enabled -to produce a skein with hardened wearing-surface; or the hardened surface may be tempered to produce a skein combining the maximum of durability and strength to be attained in a single article.

In the foregoing I have described my improved skein as having its side ed ges joined by a lap-weld,which I prefer; but it may bejoined by bringing the edges together in a butt-weld and produce an article substantially the same as hereinbefore described.

- 1 am aware that wagon-axle skeins have been made of a single piece of sheet metal, and hence I make no broad claim to such construction of device, but restrict myself to certain improvements specified in the claims.

I claim as my invention- 1. An axle-skein composed of a spindle-section and an angularly-enlarged extension or socket back of the former, the whole made from a single piece of plate metal and having but a single longitudinal seam, the meeting edges of which are secured by a weld along their entire length.

2. An axle-skein made from a single piece of plate metal and composed of a spindle-section, an enlarged extension or socket back of theformer, a short bevel joinin g the two section on the upper side of the skein.

3. An axle-skein blank ofa single piece of plate metal,without longitudinal division, having a spindle portion and an enlarged extension in rear thereof, whose edges form an angle with those of the spindle portion at the points ot'junction.

4. An axle-skein blank of a single piece of plate metahwithout longitudinal division, having a spindle portion and an enlarged extension in rear thereof, whose edges form an angle with those of the spindle portion at the points of junction and change their own direction an gularly a short distance back of those points for the purpose of forming shoulder or angular enlargements on the upper side of the skein at the junction of the spindle with the extension.

5. A plate-metal axle-skein blank composed of a tapering section and a wider section adjoining the' wider end of the former and projectin g beyond it on each side thereof.

6. A metal-plate axle-skein blank composed of the tapering section, the enlarged central section projecting at each side beyond the former, and the tapering tail-section.

7. A metal-plate axle-skein composed of the spindle portion, an enlarged extension-socket, and a bevel, in combination with the collar fitted at its back edge upon the bevel.

JOSHUA SANDAGE.
